Crash ntoskrnl.exe+ 5cd21d - driver power state failure 0x0000009f

Question

Hi,

My Pc has just recently been running into this crash and I have only been able to replicate it by putting my computer into sleep mode and then waking it up again, it will then completely disable the wifi driver and crash about a minute later.

Answer 1

Please check to see if your PC is producing any minidump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

Please do not upload a very large Memory.dmp file.

Open Windows File Explorer.

Navigate to C:\Windows\Minidump

Copy any minidump files onto your Desktop, then zip those up.

Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

Then post the link here to the zip file, so I can take a look for you.

Answer 2

The crash you are experiencing with the error code 0x0000009F (DRIVER_POWER_STATE_FAILURE) typically indicates that a driver is in an inconsistent or invalid power state. This can occur when the system is waking from sleep mode, as you've described. Here are some steps you can take to troubleshoot this issue:

1. Update Drivers: Ensure that all your drivers, especially the Wi-Fi driver, are up to date. Check the manufacturer's website for the latest versions.
2. Check Device Manager: Look for any devices with a yellow exclamation mark in Device Manager, which may indicate driver issues. Updating or uninstalling these drivers may help.
3. Event Viewer: Review the Event Viewer for any critical errors that occurred around the time of the crash. This can provide more insight into which driver may be causing the issue.
4. Power Options: Temporarily disable power-saving features in the Power Options settings. Some drivers may not handle power state transitions correctly, leading to crashes.
5. Sleep Study Report: Generate a Sleep Study report using the command Powercfg /SleepStudy in an elevated command prompt. This report can help identify what is preventing the Wi-Fi NIC from entering low power states.

If the issue persists after trying these steps, you may want to consider rolling back to a previous driver version or seeking further assistance from Microsoft support or the hardware manufacturer.
